Abstract
A method of recovering fuel vapors using a fuel dispenser having first and second sets of associated liquid flow lines, vapor flow lines, nozzles and nozzle rests includes removing the first nozzle from the first nozzle rest, inserting the first nozzle into a fill pipe of a receptacle, moving the first nozzle rest, thereby transmitting motion through a mechanical linkage from the first nozzle rest to a first normally-closed valve in the first vapor flow line to open the first normally-closed valve and turning on a first pump in the first liquid fuel line, pumping liquid fuel from a first tank through the dispenser out the first nozzle into the receptacle, and pumping fuel vapor from the first nozzle through the first vapor flow line to a manifold which has a connection to the second vapor flow line and communicates with the tanks, the second vapor flow line being closed by its normally-closed vapor valve.
